I am getting black noise in the highlight areas of my video whenever I add a video effect. Even before I make any changes to the settings of the effect, black spots appear in the white (highlight) areas of the video. Toggling the effect on/off from the effect control window makes the spots appear/disappear.
Any suggestions as to why this is happening and how to eliminate the problem?
I am using Premiere Pro in CS6 on an iMac computer.
Thanks!
